| Research Abstract |
We examined the signal transduction pathways in the brain involved in the recall of food memory. When human and animals eat some foods followed by malaise or nausea, they learn the taste of the foods as the signal of danger and became to dislike the foods. This phenomenon is referred to as conditioned taste aversion(CTA). In this study, we found the changes in the activities of the signal transduction pathways in the brain after CTA, suggesting that the plastic changes in the brain network are involved in the shift in feeding behavior(from like to dislike).
